It is composed of what sounds like a bizarre mixture: fly-ash, a fine-grained waste product from coal-fired power stations; carbon nanotubes, cylindrical molecules made of elemental carbon; and two binding agents, sodium silicate and sodium hydroxide.

煤灰，火力发电厂排放的细颗粒废弃物；碳纳米管，即柱状的碳分子；还有两种黏合剂：硅酸钠和化钠。

However, in terms of general usage, the word 'bleach' is used to refer to common household bleach, which consists of 3-8% sodium hypochlorite and trace amounts of sodium hydroxide.

就一般用法而言，“漂白剂”一词是指普通家用漂白剂，由3-8％的次氯酸钠和微量的化钠组成。

As well as strong bases, like sodium and potassium hydroxide.

及强碱，如化钠和化钾。

You could technically have an even higher pH. A really high concentration of sodium hydroxide in water can have a pH of 15, which means there’s only 1 hydrogen ion for every 100 million hydroxide ions.

理论上你有更高的pH值。水中极高浓度的化钠达到pH 15，这意味着每1亿个离子中只有一个离子。

And in that remember we're looking at the amount that we have to add of a certain solution, in this case is was sodium hydroxide.

记住, 我们正在考虑必须添加的特定溶液的量, 在这种情况下是化钠。

This is done by soaking them in water or brine or brine followed by a solution of sodium hydroxide known as lie.

这是通过将它们浸泡在水中或盐水中，然后再用一种称为碱液的化钠溶液来完成的。

These chemicals are Sodium hydroxide, which is a base.

化钠，它是一种碱 碱。

Supposedly, this alters the chemical composition of the baking soda to make it perform more like lye.

据说，这会改变小苏打的化学成分，使其更像化钠的效果。

So that's like, 294 Kelvin, and now I shall add my 100 mL of sodium hydroxide.

所那是大约294开尔文，现在我将加入100毫升的化钠。

Remember that we can look up the standard enthalpy of formation for all the products and reactants in the back of a textbook or online, the chemical reaction between hydrochloric acid and sodium hydroxide produces liquid water and sodium chloride.

记得我们在教科书的后面或在线查找所有产物和反应物的标准生成焓，盐酸和化钠之间的化学反应会产生液态水和氯化钠。

The real way to do this is to use a food grade lye, but we're doing a work around of baking soda that has been previously baked in the oven at 250 degrees Fahrenheit for an hour.

真正的方法是使用食品级化钠，但我们这里用的是之前在烤箱中250华氏度烘烤了一小时的小苏打作为替代。

She then left the olives to soak and sample them from time to time until 273 days had passed This being the normal period for which olives are stored in brine prior to processing with lie.

她然后让橄榄浸泡，并不时品尝，直到273天过去。这是橄榄在用化钠处理前，通常在盐水中储存的正常时间。

If instead of adding 30.0 milliliters of 1.0 molar sodium hydroxide, let's say we had to add 25.0 milliliters of a 0.5 molar sodium hydroxide solution.

如果不是添加30.0毫升1.0摩尔化钠, 假设我们必须添加25.0毫升0.5摩尔化钠溶液。

Remember I told you it's 1.0 molar sodium hydroxide solution.

记得我告诉过你这是1.0摩尔化钠溶液。

The standard enthalpy of formation for hydrochloric acid is -167.2 kJ per mole; for sodium hydroxide it's -469.15 kJ per mole; for liquid water it's -285.8; and for sodium chloride it's -407.27.

盐酸的标准生成焓是-167.2千焦每摩尔；化钠的是-469.15千焦每摩尔； 液态水的是-285.8千焦每摩尔； 氯化钠的是-407.27千焦每摩尔。

(mumbling) And now I'm going to put the same amount of sodium hydroxide solution.

（咕哝着）现在我要加入相同量的化钠溶液。

As we add the sodium hydroxide, the pH is going to start to climb gradually.

当我们添加化钠时，pH 值会开始逐渐上升。

What we're going to do is be adding sodium hydroxide to hydrochloric acid.

我们要做的是将化钠添加到盐酸中。

Then, there's sodium hydroxide, another substance that I wouldn't wish to be on my worst foe, although I'm glad we have it.

然后是化钠，另一种我连最恨的敌人都不希望它有的物质， 尽管我很高兴我们有它。

And so in this case we're going to have acetic acid in the bottom and then we're going to add a strong base, so that's sodium hydroxide.

在这种情况下， 我们将在底部加入乙酸， 然后添加强碱，也就是化钠。
